Good site, works ok and you get what you order, no problems experienced, got my manual within a day. A++++

Original well scanned manual. Got the job done. Microwave problem found & corrected. For $5 and a new magnitron from ebay, it was a cheap and good the first shot fix. Electrical schematics allowed me to mage sure every thing else was ok before cutting and order for parts. Hard to live without.

I was very skeptical of this website, I have never downloaded manuals before. I put it on the AMEX and payed through Paypal to ensure protection. I got the manual exactly as described and now I can replace the filter capacitor for this amp. Great Price, others selling for 12.99 or more and this is the same manual. I will search out this website for other manuals. Thank you
CIRCUIT OPERATION
1-3) PB MODE
When playing the tape, the signal which is picked up from the tape is amplified 50 dB. Then luminance signal goes to pin 11 and color signal goes to pin 7 through AGC. Luminance signal of pin 11 is input to pin 39 of IC301 through PB EQ circuit in order to match playback characteristic. Color signal which is output from pin 7 of IC401 is input to pin 15 of IC301. PB FM signal is demodulated by IC internal demodulator then it is input to pin 3 after MAIN DE-Emphasis process. If this output signal has burst, color component will be separated by X303. If it has burst, it is input to pin 4 of IC301 through Yemphasis circuit. The signal which is input to pin 4 is output from pin 12 through 3.5M LPF, then it is input to pin 10 through 1H CCD. Color signal which is input to pin 15 passes ACC in order to stabilize level, then 3.58H components will be extracted by 3.58M BPF through Main Converter. This 3.58M color signal is input to pin 25 of IC301 in order to eliminate crosstalk, then it will be mixed with luminance signal after passing CNR circuit. Finally Y/C composite video signal is output from pin 34.
